例句与用法

1. The implementation of such a system is extremely complicated due to three factors : the impulse response of a lrm system have a duration of several hundred milliseconds , the system has to be adaptive , and the adaptation has to be performed with a speech input the traditional adaptive algorithms such as lms and nlms can not obtain the satisfied result in the real - time acoustic echo cancellation processing
   但由于声回授通道的特殊性和复杂性，普通的自适应算法无法满足要求，必须采用一些十分复杂的算法，这样一来，实时性的问题变得十分突出。快速lms newton算法的提出，给自适应声回波对消问题的解决开辟了新的途径。该算法集lms算法的简单易行性和newton算法的快收敛性为一体，是一种非常有应用前景的自适应算法。
